摘要: Abstract Spectroscopic data for all nuclei with mass number A=136 have been evaluated and the corresponding level schemes from radioactive decay reaction studies are presented. No excited states known in 136In, 136Eu, or 136Gd 136Tb remains unidentified. Discrepancies between experiments on isomeric decays 136Sb 136La suggest need futher experimental investigation. The of 136Eu has only observed a mixed source. energy 17.5 s isomer 136Cs was determined since last evaluation, however, branching ratio unknown. This work supersedes earlier full evaluation by A.A. Sonzogni (2002So05), benefited tremendously previous evaluations A=136.
